An anchor system with a bridle substrate and harness configured to attach to an anchor line. An outer bladder surrounds an inner bladder for coupling on top of the bridle substrate. Water enters the anchor system through a water inlet that feeds directly to the inner bladder and fills that first. Water then overflows from the inner bladder to the outer bladder to fill that second. The inner bladder provides stability and is positioned with a majority of its volume closer to an uphill end of the anchor bladder while the outer bladder is positioned with a majority of its volume closer to a downhill end of the anchor bladder. Reinforcement connectors for each bladder resist deformation of the bladders to resist movement of the anchor bladder while filling.

Offshore terminal apparatus which in various examples comprises a floating storage vessel which is spread-moored in fixed heading orientation to a seabed offshore by spread mooring lines, the floating storage vessel comprising a hull having bow and stern ends and which at either or both the bow end and the stern end is fitted with an extension section and includes coupling means on the extension section to couple spread mooring lines to the floating storage vessel.

A foundation for a subsea assembly is provided. The foundation includes connection points. The connection points permit other components to be connected to the foundation and permit loads to transfer from the other components into the foundation. The foundation may be a suction anchor. A method of converting an exploration well using the foundation to a production well is also provided.

A floating power-generation group comprises a floating hub such as a spar buoy that is anchored to subsea foundations by anchor lines. Floating power producer units such as wind turbines are connected electrically and mechanically to the hub. The power producer units are each moored by mooring lines. At least one mooring line extends inwardly toward the hub to effect mechanical connection to the hub and at least one other mooring line extends outwardly toward a subsea foundation. The groups are combined as a set whose hubs are connected electrically to each other via subsea energy storage units. Anchor lines of different groups can share subsea foundations. The storage units comprise pumping machinery to expel water from an elongate storage volume and generating machinery to generate electricity from a flow of water entering the storage volume. The pumping machinery may be in deeper water than the generating machinery.

A system (100) and method for mooring and anchoring of floating solar panels (150) on water surface is disclosed. The system (100) has a floater unit (154) for securing the solar panels (150), The floater unit (154) has securing means (152) along its circumference. Buoys (122, 124, 126, 128) are floated on the surface of the water body such that each buoy is anchored to at least one anchor (142, 144, 146, 148) at a floor of the water body. Main mooring lines (112, 114, 116, 118) are connected to the buoys (122, 124, 126, 128). A parabolic curve is formed by connecting one end of the adjacent main mooring lines to the same buoy. A plurality of connecting lines (162, 164, 166, 168) are used for connecting each main mooring line (112, 114, 116, 118) with the securing means (152) at corresponding side of the floater unit (154).

A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.

A system for tethering a subsea structure includes an anchor embedded in the sea bed, a mud mat disposed partially above the seafloor, a link attached to the anchor and to the mud mat, and a flexible tension member. One end of the flexible tension member is coupled to a tensioning system configured to pay in and pay out the flexible tension member. The tensioning system is mounted on one of the subsea structure or on the mud mat. The other end of the flexible tension member is coupled to the other of the subsea structure or on the mud mat. The anchor may optionally be buried below the seafloor.
